Try to remove all temporary files (.ncb, .clw, .plg, .aps, .clw, .opt, ...)

Have tried all that already thinking it might be the opt file especially but it didn't help. Even deleting the entrie project and getting it fresh from Source Safe (no temp files in there naturally) never helped.

However something must be kept somewhere to make it do this.

Happy programming!!

Bad Invalidate ...

I've got a resizing Dialog inside sizing control bar ( using the great CSizingControlBar
from Cristi Posea ) and inside the dialog I have a few edit controls ( either simple
controls, or RichEdit, or CEdit embeded in a custom control ). When resizing the control
bar, the edit boxes loose their 3D borders, and if I move a window over them, they get
partially repainted.

When I resize the controlbar, I can see the borders beeing redrawn, and then drawn
over...

This look like a bad invalidate somewhere ... but I even have an invalidate at the end of my OnSize callback.

The hierachy goes something like this : ( from the outside going in )

ControlBar
CWnd ( PlaceHolder )
Dialog (auto-resizable dialog base class )
CEdit ( bad redraw )
CButton
Dialog (same auto-resizable base dialog class as the Cdialog above)
CEdit ( bad redraw )

Any clue ? I've seen this before but I can't remember how I fixed this ...

Main window is hiding

Hi !

Let's say I pop up a dialog from the main window like this:

CVpdDisplayDlg *vpd_disp=new CVpdDisplayDlg (data_base,this);<br />
	vpd_disp->Create(IDD_VPD_DATA,this);<br />
	vpd_disp->ShowWindow(SW_SHOWNORMAL);

After that, when the main window is hidden by the new one, if I move the new one to the side and click on the main window, it will not pop back up ??????????????????????

This should be an easy one for Windows experts.....

Thank you

IF the dialog is the child of the main window, it will always display above it. Pass NULL as the parent if you do not want this, but remember this means your dialog will be lost behind it's real parent.

Sockets which listen...

I'm a bit of a beginner on Winsock programming. I've done some simple apps which connect to a server/client etc., on a given port, transfer data blah blah. However, I'm curious how programs work that listen on 'any port'. For instance, if I want to write a program that looks for 'a connection' and then can report to me on what port that connection is being attempted, how do I go about doing that? Since there are 65,535 tcp ports, how does one listen to all of them simultaneously? Or am I going about this the wrong way?

File Monitor Source Code

hi I've looked at FileMonitor by franky braem, it looks good but when i compile it i get an error message... and it debugs on the line

HRESULT hRes = pUnkCP->QueryInterface IID_IConnectionPointContainer, (void**)&pCPC);

thats in the atlbase header file, which is

ATLINLINE ATLAPI AtlAdvise(IUnknown* pUnkCP, IUnknown* pUnk, const IID& iid, LPDWORD pdw)<br />
{<br />
	CComPtr<IConnectionPointContainer> pCPC;<br />
	CComPtr<IConnectionPoint> pCP;<br />
	HRESULT hRes = pUnkCP->QueryInterface IID_IConnectionPointContainer, (void**)&pCPC);<br />
	if (SUCCEEDED(hRes))<br />
		hRes = pCPC->FindConnectionPoint(iid, &pCP);<br />
	if (SUCCEEDED(hRes))<br />
		hRes = pCP->Advise(pUnk, pdw);<br />
	return hRes;<br />
}

Does anyone know why this is happening? do i have to set the project up differently as it is using atl objects, or is it because i'm now using windows xp pro and not windows 98...

Thanks - Jason

What you say is both untrue and badly described.

I've taken the time to recompile the FileMonitor code by franky, and :
- it compiled fine
- there is no AtlAdvise call in his code

Not only I don't see where the problem is, but here are my points :
- in case of a problem with a CP article, why not post in the comment area associated to that article, so to make sure the author can help you
- there is no AtlAdvise call, so there is no relation between your post and the actual code you refer to
- you forgot to replace < by < in your post. It's impossible to understand it.
- you begin your post saying you have problem compiling something, and finish your sentence saying "it debugs on the line". So what is it actually ? compiling problem or run-time problem ?

This post is definitely a poor rate.

Sorry.
Why do you take that so personally? You're right in that I made an error it does compile and there is a runtime error on my computer.
It is an unhandled exception at 0xC0000005 : Access Violation, and when I debug the program it returns me to the ALTBASE.H file and points at the line I said. I know this function isn’t called directly from the source code however it obviously is called from another function in one of the header files or I wouldn’t be getting this error message and debugger wouldn’t point me to this line.
So next time you reply please consider that some of us aren’t as good at programming as others and try and help, constructive criticism is fine, but please try not to be so offensive.. Also I’m using visual c++ v6.0 for anyone who might be able to help.
One final thing, both the release version and the debug version of the compiled program already (compiled) also gave me this error, so why is this? It has to be my operating system which differs to the one used when the program was compiled is this true?
Please help as I’ve not been programming long, lame excuse I know but hey we all have to start somewhere.

Editing list view subitems

Jay21-Nov-02 11:54

1-Nov-02 11:54

Ok i'll have a look at that. I've not had time or I've been going too fast about things to realise that I meant franky braems' TempMonitor, I probably got confused between filemonitor and temp monitor.

My aims are to write/ change a program to:-
Allow it to run in the background which can provide a report of all files accessed and modified at any time!

This way i should be able to see where any program has updated it's settings and probably change these settings back to there original settings by simply copying the files back where they came from.

I'd already written simplistic exe encapsulating programs, (like viruses that dont do anything) and i was hopeing that i could alter this to encapsulate the exe allowing for the program to revert it's settings back to previous loaded version automatically, it should be simple and this way it would be possible to bypass any evaluation period on the software that I'm dealing with without too much hassle (microsoft only for what they did with virtual engine and sun).
The only way is to find out what files have been changed and I'd prefer to program an application that does this rather than search the internet for one.

Sending Email

Hi !!
I like to develop application in VC++ to send email. But i neither want to use MAPI nor I want to use any SMTP server. There are excellent articles here by PJ Naughter to send maill using MAPI and without using MAPI. But i want my application not to use any SMTP server and I want it to send mail directly. I hope that it is possible if one is connected to internet. Is there any sample application you aware of present somewhere ????

Read the RFC's 821, 822 and 2045[^] .

Connect to the outside mailhost and communicate directly with it via TCP/IP using WinSock 2.

This can be done using telnet, by hand, if you know what you're doing Wink | ;)

BTW, you will eventually use an SMTP or other type of mail server, just closer to your email destination.

I'm not following you. You can write your own class or application to send mail, but you're gonna have to connect to some kind of a mail server at some point. To my knowledge, the only way to NOT use an SMTP server (or other kind of mail server, as most internet mail is SMTP) is to be your own smtp server and become registered as such.

Why do you not want to use an SMTP server? You can write a class which talks directly to your outgoing mail server (just like every other email client in the world) with not too much work communicating directly with the CSocket class.

He might be trying to get around the problem that many ISPs require you to be connected to them in order to use their SMTP server. It's not sufficient to just supply a username and password.

You're talking about the relaying issue, I assume. Yeah, it seems like trying to hit a finishing nail in with a sledgehammer to void using SMTP servers to deliver email.
